Cultivation details

Management: Standard  New Perennial Crop  Staple Crop: Oil

Climate: tropical. Humidity: humid. A rain forest species for truely wet lowlands. Cultivation: new crop. Management: standard (Describes the non-destructive management systems that are used in cultivation) [1-1].

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • New Perennial Crop  Most new crops were important wild plants until recently, although some are the result of hybridization. They have been developed in the last few, decades. What they have in common is that they are currently cultivated by farmers.
  • Staple Crop: Oil  (0-15 percent protein, 16+ percent oil). Some of these are consumed whole while others are exclusively pressed for oil. Annuals include canola, poppyseed, maize, cottonseed, sunflower, peanut. Perennials include high-oil fruits, seeds, and nuts, such as olive, coconut, avocado, oil palm, shea, pecan, and macadamia. Some perennial oil crops are consumed whole as fruits and nuts, while others are exclusively pressed for oil (and some are used fresh and for oil).
